Answer 1

You have to use semicolon ; in between clauses like $expand=primarycontactid($select=contactid,fullname;$filter=contains(yomifullname,'arun'))

Try this:

https://crmdev.crm.dynamics.com/api/data/v9.0/accounts?$select=accountid,accountnumber,name&$expand=primarycontactid($select=contactid,fullname;$filter=contains(yomifullname,'arun'))&$top=3
